Combination of porous spinning or twisting rings with a ring rail and common lubricant supply

ABSTRACT

A porous spinning ring and holder of a selected diameter is mounted on a ring rail of greater or lesser width and the holders and rings are connected with a common source of lubricant in the form of a pipe extending along the front or rear of the ring rail. The ring holder has a lateral extension of at least a minimum length and the holder may be rotated within limits on the ring rail to a position at which the effective connecting point of the extension will be directly over the lubricant pipe and the extension and pipe can be connected. The connection and the holder extension have passages in series leading from the pipe to the porous ring for the transmission of lubricant. Identical ring holders and rings mounted thereon may be used on ring rails of differing widths within limits and still be connected by identical means to a common source of lubricant.

v RINGS WITH ARING RAIL AND COMMON LUBRICANT SUPPLY ancxonounoor THE INVENTION of being able to purchase a quantity of identical rings and holders having the same size=lateral extensions for connection "The use of spinning and twisting ringsmatle of porous 'materialis now a generally accepted practice in the textile industry. Thelubricant for the-rings is usually supplied through the use of an individual reservoir which is a .part of each ring ,holder. Since the periodic individual filling'of each [reservoir on each ring holder is a time-consuming requirement of operation, the art shows the .development of means for utilizing a common source of oil supply usually in the fonn of a pipe v running the length of the ring rail with individual connections I'llnningfrom the pipe to each ring holder through which'the oil passes to'the porous'rin'g. All of thearrangements in the prior art in which a common source of oil is used requires special connections foreach width of rail and 'each size of ring used therewith. g v v The present invention is designed tobroadenthe utility of the concept of supplying 'oil to the rings on a spinning frame .through'a-common source whereby identical rings and ring holders may be utilized on ring rails of different widths and still capable of connection by u'niform'connecting means to an oil supply pipe extending along one side of the ring rail. For convenience of description hereinafterthe pipe will be"c'onv sideredas being at'the front of therail. When reference is made to ring rails of different widths, it is contemplated that the size of ring reqitired on these rails will be the same but that the axes of thejispindleswillbe differing distances from the.

face of th el'railthereby necessitatiii'g positioning the rings at correspondinglydifferent distances from the-railface'. b In furtherexp lanat ion of the invention, it willj'be appreciatcd that each holder has some'type ofidentical lateral extension having a passage ther'ethrou gh through which the oil travels to th'e ri n'g l If rings a'n'dholders of identical size should be used on a narrow ring rail,- the extensions would extend farther'beyond the front face of the 'railthan would the case I if the same identical holder and'ring were placed on a wider ring raiL- In the first case, if the extensionswere to be con.- nectcd to a common-source of oil in the form of a piptnthe pipe wouldnecessar'ilybe located a distance away mm theface of the ring rail, whereas-in the second'case the extension would extenda lesser distance beyond the fa'ce'of the ring rail so that the connections of the extensions to the .pipe 'might' enable the pipe to be directly against the face of the ring rail.

.Thus'under thec nditions just described, it is obviousthat mounting identicalholders and rings on ring rails of different widths would require different locations of the supplypipc nnections were to be Thus according to the present invention, it is contemplated the face (front or rear) of the ring rail, an'd'the effective points limited rotation of the holder. After each holder has been brought to the proper position by rotating it about its center which also coincides with the axis of the spindle, the holders are then clamped to the ring rail in permanent position and each connecting means is passed throughthe holder extension and screwed into a threaded hole in the top of the pipe.

1 SUMMARY OF THE INVENTION The invention contemplates the use of identical holders and spinning rings of porous material which may be connected with a common source of oil supply on spinning frames in which the ring rails-are within limits of different widths. On the widest ring rail with which the holder can be used, the lateral extension of the holder will be positioned along a radius which is at right angles to the line of the spindles. As the holders are used on narrower-ring rails, theholders will be rotated sufficicntl'y to bring the effective point of connection of each extension to a position directly over the centerline of the common oil supply pipe]. With the. connections made between the pipe the extensions and the holders with all of the latter anchored in position on the ring railat the correct angular means is required. 9 I

Regardless of thc angula'r position of the holders as required by the distanceof the spindleaxis' from the rail face, the same connection can bc niade-betwcen each extension and the oil pipe. In other words, identical holders and connections-may be used to cover a range of differing ring rail conditions.

As to the utility of this invention, it is common to find under I one roo fin a spinning' mill, spinning frames having ring rails of different widths even though these frames maybeutilizing holders and -ringsof identical diameter.; Thus, if ,such mill proposes to convert the lubricationof its rings from an in- H dividual oil supply'for each ring to a common source, instead located under and within the ring rail edge flange.

DESCRIPTION THE PREFERRED EMBODIMENT As has been previously pointed out, the object of the invention is to make use ofuniformsized ring holders and rings on the ring rails in which the ring rail hole may, within limits, be a varying-distance from the face of the rail, andby the construction disclosed herein make it possible to have uniform connecting means whereby each holder may be connected with a common source of lubricant in; the form of a pipe running along the face of the;- ring rail. While the pipe is shown as an element independent of the rail, it is to be understood that the two could be made as an integral unit.

Referring now to FIG. I, thereis shown a ring raiI 2 having itsfront'face at 4 and its rear edge at 6. The ring rail hole through the ring rail'is indicated at 8 and the axis of the spintile is at'l0. I Y

Mounted on the rail in conventional positions are a seriesof ring holders 12 two of which are shown in FIG. 1. These holders are identical, indimension and are the same size as the two holders show ;in FlG -2, will be referred o hereinafter. I

Alongthe face 4 pf ring rail 2 is a horizontally extending form although it will be understood that it could be round or in other section if preferred. It could also be in the form of a bore extending longitudinally through the body of the rail as shown in FIG. 6, or as a separate pipe under the ring rail as in FIG. 7.

Each holder 12 has a lateral extension 16 having an effective connecting position the center of which is indicated at 18 which is located over a corresponding connecting position along the centerline of pipe 14. The holders 12 are held in their final properposition by any of the conventional means new in use such as for example a pair of clamping screws 20 and 22 and guiding lugs 24 and 26. Thus when the extensions 16 are suitably connected to the pipe 14 which as stated is against the face 4 of rail 2, the holder-securing means may be set up tight on each of the ring holders. Thus all rings on rail 2 will have their extensions overlying the pipe 14 at a uniform angle and the spinning frame is then ready for operation.

The construction shown in FIG. I is representative of a rail in which the ring rail hole 8 and the spindle center are at a minimum distance from the face 4 of the rail using holders and rings of uniform size. As distinguished from FIG. I, FIG. 2 shows a situation in which the ring rail hole and the spindle center are at a maximum distance from the face of the ring rail using the aforesaid uniform-size holders and rings.

In FIG. 2, the ring rail is indicated at 2', the front face of the rail at 4', and the rear of the rail at 6. The ring rail hole is at 8 and the spindle axis at 10. The holders 12, however, are exactly the same as the holders shown in FIG. 1. Since the spindle axes 10 in FIG. 2 are at a greater distance from the face 4' of the ring rail, it is necessary for each holder to be rotated to the left until the center 18 of the effective point of connection is located over the centerline of pipe I4 and extension 16.

When in FIG. 2 all of the holders have been arranged as shown with respect to the ring rail and the pipe 14 and have been connected with the pipe, then the clamping screws 20 and 22 may be set up and the rail will be ready for operation.

From the foregoing explanation, it is believed clear that holders and rings carriedthereby may be used with equal effectiv'eness on rails in which the distance from the effective point of connection of the extension to the spindle center may vary from a minimum distance A indicated in FIG. 1 to a maximum distance B indicated in FIG. 2. It is possible in all cases where the distance from the ring center to the edge of the rail is not less than A nor more than B to connect the extensions 16 appropriately with uniformly spaced holes in the oil pipe 14. To achieve maximum utilization, it is preferable that the pipe 14 occupy a constant lateral position against the face 4 or 4 of the ring rail even though the longitudinal position of pipe 14 may have to be shifted to bring the threaded pipe holes into alignment with the effective points of connection of the extensions 16. The distances between the effective points of connection of each extension to pipe 14 will be the same as the distance between the spindles.

Further details of a preferred means of connecting the holder extension and pipe 14 together whereby oil may pass from the supply pipe through the extension to the ring are shown in FIGS. 3, 4 and 5.

The spinning ring 13 in FIG. 3 is made of porous material and is representative of conventional horizontal-type rings now in use. It need not be described in detail except to say that arrangement is made to supply oil under pressure which will travel upward through a vertical opening 28 to a circular groove 30 in the top of the ring. This groove is covered by an annular plate 32 to prevent escape of the oil over the top of the ring. The oil passes from groove 30 through the porous ring to reach the outer surfaces thereof that need to be lubricated to minimize wear of the traveler.

Ring 13 is shown as positioned within holder I2 and a Y lateral passage 34 is in alignment with passage 36 that extends radially through the extension 16 to terminate at a vertical hole 38 near the end of the extension I6. When the extension 16 is at the correct angular position according to the distance of the axis of the spindle from the face of the ring rail, the effective center of connection 18 will be aligned with the center of the threaded opening 40 extending downwardly through the top wall of pipe 14. The upper end of hole 38 preferably has a shoulder 42 on which may be positioned an O-ring 44 used for sealing purposes. The means which connects pipe 14 and extension 16 also serves to put the pipe passage 46 in fluid connected relation with the passage 36, is a plug generally referred to at 48 having at its upper enda peripheral flange 50 which rests on the O-ring 44. The lowerportion of connector 48 is threaded at 52 to make proper screw-threaded engagement with the threads 40. A vertical central passage 54 extends upward through the connector 48 to terminate at a crosswise extending passage 56 the ends of which open into a circular passage 58 which circular passage regardless of the angular position of connector 48 leads to passage 36 in extension 16.

A second O-ring 60 surrounds the connector 48 and lies between the underside of extension 16 and the top of pipe 14. A conventional hexagonal opening 62 in the top of connector 48 is adapted to receive a conventional so-called Allen wrench whereby the connector may be screwedinto the threads 40 and, when set up tight, the O-rings 44 and 60 will be sufficiently compressed to provide an oiltight connection. Another O'ring 64 may be used at the juncture of passages'34 and 36 to prevent leakage between the base of ring 13 and the holder 12.

It will be appreciated from the foregoing explanation that the invention is only applicable to ring holders having lateral extensions or the equivalent thereof which on a narrow ring rail would extend beyond the oil supply pipe when set at right angles to the line of the spindles and which on a wide ring rail would be long enough to reach at least as far as the oil supply pipe. The invention also requires that there be means whereby the holders and associated rings may be accurately rotated about the holder axis (which coincides with the spindle axis) thereby to bring the effective point of connection of the extension over the centerline of the oil pipe. The oil pipe may have all of the threaded openings made therein prior to being positioned against the face of the ring rail since the distance between the openings will necessarily be the same as the distance between the spindle axes. The pipe 14 may be held against the face of the ring rail by any suitable type of clamping mechanism which will permit the pipe to be shifted axially until the centerline of the pipe hole intersects the are or rotation of the center of effective connection of the extension.

In FIG. 5 is shown a vertical-type spinning ring 66 mounted in a holder 68 from which protrude extension 70 which is connected to pipe 14 in the same manner as extension 16. Passage 72 leads from circular passage 58 to the wicks 74 which carry the oil around thering in known manner.

It will be appreciated that the angle between the radius running from the spindle axis 10 to the effective point of connection 18 of the extension 16 and the line of the spindles will be that angle whose sine is A/B. Since these distances are determinable in advance, the holders may all be angularly preset in position on the ring rail with the knowledge that when the pipe 14 is correctly positioned longitudinally, all connectors 48 may be screwed into pipe 14 through extension 16.

When reference is made herein to spinning frames and spinning rings, it will be understood to include twisting frames and twisting rings which function in the same manner. Furthermore, when reference is made in the claims to a lubricant supply pipe along the edge of the rail, it is intended to include not only a separate pipe such as that shown in FIGS. 1, 2 and 3 which may be shifted longitudinally along the outer side of the rail vbut also a pipe which is an integral part of the rail as shown in FIG. 7 and in the form of a bore extending through the body of the rail.

Another alternative construction tobe considered as within the scope of the claims is a separate pipe located under the rail and inside the flange at the edge as shown in FIG. 6.

Modifications and further applications of the invention will now be apparent to those skilled in the'art without departing from the spirit of the invention.
